工具 | sftp 的简单了解

Secure File Transfer Protocol，安全文件传输协议。
相比 ftp 降低了速率，提升了安全性。

• 连接
  默认端口为：22

sftp -oPort=1022 username@ip

• 常用命令
  pwd、ls、cd、mkdir等命令类似于本地服务器的操作，关键是get，put两个命令

• 下载文件到本地服务器

get [-afPpRr] remote [local] # -r: 下载目录及以下文件

• 上传文件到远程服务器

put [-afPpRr] local [remote] # -r: 上传目录及以下文件

• 对本地服务器的操作
  !cmd: 命令前加 ! 对本地进行操作
  lls 或 !ls: local ls
  lpwd 或 !pwd: local pwd

• 退出远程服务器
  bye、exit、quit、^D
